Abstract: Objective: A facile, effectively and environmentally friendly method for preparation of well dispersed silver nanoparticles was reported.

Methods: In the method, Capsicum annuum L. extract was used as both reducing and stabilizing agent without addition of any other reducing and capping agent. The generation of silver nanoparticles was found by alteration of color from light yellow to red and the UV-vis absorption spectroscopy. The effect of extract and silver nitrate amounts on the formation of silver nanoparticles was investigated.

Results: The shape of the as obtained silver nanoparticles was determined by using TEM and SEM, which illustrated that the silver nanoparticles are global in shape with a narrowly distribution from 5 nm to 25 nm.

Conclusion: The crystalline structure of the silver nanoparticles was examined by XRD and FT-IR analysis, which showed that the silver nanoparticles were highly crystalline of nature and coated with biomolecule.
